Anchoring method and anchoring device penetrating through water-rich sand layer
The invention relates to the field of civil engineering construction, in particular to an anchoring method and anchoring device penetrating through a water-rich sand stratum.The anchoring method comprises the steps that S1, the area of the water-rich sand stratumin a side slope is ascertained, and an anchoring area is determined in a stratum; s2, a fixing pile is implanted in the anchoring area; s3, a hole is drilled in the side slope through a casing pipe, a fixing pile is drilled in the casing pipe, and hole washing operation is conducted; s5, a separable inner pipe is arranged in the casing pipe, the anchoring part extends into the fixing pile from the inner pipe, the casing pipe is pulled outwards by a set distance, and the end of the casing pipe and the end of the inner pipe are located at the section, facing the hole opening of the drill hole, of the fixing pile; s6, the casing pipe is taken out; and S7, grouting the inner side of the inner pipe. According to the method, the anchoring acting point of the anchor rod is optimized, grouting is conducted through the inner pipe, and the problems existing in the prior art are effectively solved.
本发明涉及土建施工领域，尤其涉及一种穿富水沙层的锚固方法及锚固装置，锚固方法包括：S1、探明边坡内富水沙层的区域，在地层确定锚固区域；S2、在锚固区域植入固定桩；S3、在边坡通过套管钻孔，套管钻孔入固定桩，洗孔作业；S5、套管内设置可分离的内管，将锚固件由内管伸入并伸至固定桩内，将套管外拔设定距离，套管和内管的端部位于固定桩朝向钻孔的孔口的一段；S6、将套管取出；S7、向内管内侧注浆。本发明通过优化锚杆的锚固着力点，采用内管进行注浆，有效的解决了现有技术中存在的问题。
